[PATCH] D105119: [SVE] Fix incorrect codegen when inserting vector elements into widened scalable vectors

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

For non-scalable vectors, widening means we pad the end with undef elements (i.e. INSERT_SUBVECTOR into an undef vector).  Do you want it to mean something different for scalable vectors?  Is this documented somewhere?
